System File Checker (SFC)

By megahertz ·
I have a question regarding the SFC /scannow command.

If the original CD that came with the computer is Windows XP SP1 and the machine now has SP3, when I run SFC, a damaged file on the machine should be replaced with a good file from the CD BUT the files on the CD are obsolete since they are from an earlier service pack. How does SFC handle this?

In other words, does SFC have to be run using only the SAME version and service pack CD as the version installed on the machine?

Appreciate any pointers.
Thank you, Jay

Either way

You can use the original. If you are concerned it will back date files, try using this method and see if it will install also.

When you run SFC it replaces any Damaged/Modified Files

Back to what is on the Install CD. So if you where to run SFC on a SP3 and use a Original XP Install Disc it would remove the SP3 Files and replace them with the Original XP Files and when it was finished you would then need to reapply the Service Packs and any Hot Fixes to update the system.

Alternatively you could make a Slipstreamed Disc and include the Service Packs with a product like nLite

Just make sure to read the directions here

And then use that when you run SFC. That way it would keep the newest Service Pack Files at least. But if they are the cause of the problem it would not fix the problem.
